What you do here doesn't matter, only what God has done in you and what He can do in others. Let His Spirit give you the Victory!
These Christian tips should help explain the rules:
Basic Yu-Gi-Oh strategy is revealing what your chosen characters are doing as they interact with the space around them. For instance, the strategy of Zefras is encouraging others to trust in the salvation of God's Word due to the angels God sends through the power of His Word and His Spirit. So you would add cards that would support that notion of trust like Grand Horn of Heaven, or Recall, or Solemn Warning. You could also add cards that are trusting in the angels of the Lord to do what they do; like Symphonic Warrior Rockks, or Seraphnite, or Proxy F Magician, or Zefra Metaltron.
On the other hand, Gravekeepers' strategy is about including others in the participation of anticipating the promise of our eternal lives in Heaven. So you would add cards that would support that notion of including others. Cards like, Book of Eclipse, the Selection, Cup of Ace, Present Card. You could also include cards that support trusting in God's promise of eternal life through Heaven like Desert Sunlight, Blessings of the Nile, Imperial Tombs of Necrovalley, Necrovalley, Stelle, Grand Horn of Heaven, Kahyo-rai-getsu, Flash Fusion, Kuribohrn, and Master Peace, or Metaltron 12.
On the contrary, the strategy of something like Archfiends would be trying to get others to believe in their gained abilities by trusting in what they earned for themselves by relying on satan. So cards that focus on selfishness or what satan can give would probably be ideal. Cards like Solemn Strike, Ash Blossom and Joyous Spring, or Sakuretsu Armor.
A card's Attack or Defense is the willingness of the card to share what God has given to it. Either its' willingness to give to others (attack) or its' willingness to accept what others share (defense). Sometimes these stats can be increased or decreased as they trust in other things instead of what is just given to them personally. Either by trusting in what God is doing in others or believing in other things that God has done. Or by trusting in what satan does or what it can do to others.
Cost is simply acknowledging that players cannot abuse their cards thus accepting how the cards are interacting with each other since the cards wouldn't take back believing in what a card does or trusting in what a fellow teammate could accomplish.
Star/Star Level is how the card is connected to the Word (Christ). This allows other cards to trust in how others are connected to the Word. For instance, with Synchro summoning cards who are connected to the Word differently (having different levels) can trust in the abilities of someone else who is connected to the Word in a different way than them. When Xyz summoning, cards can trust in the abilities of someone who is connected to the Word in the same way as them. When fusion summoning, cards trust in the abilities of someone else based on how they are connected to that other individual. This is independent of their level or how they're connected to the Word or Christ. Because Link monsters are supposed to be trusting in the connection to the Word via their Spirit, they don't have levels. When Pendulum Summoning, cards can also trust in other cards' connection to Christ by having faith in God. Tribute summoning is simply when the cards have faith in what another card can do and isn't really dependant on their connection the Word.
